Pole count.

Also written number of poles, pin count, contact count.

What does pole count mean on a connector?

Pole count is the number of separate electrical contacts a connector carries, so a 4 pole M12 has four pins and a 12 pole terminal block clamps twelve wires. It is fixed by the circuit: power needs few poles and heavy contacts, a sensor bus needs more and finer ones. Match the pole count and the coding to the device before choosing anything else about the part.
